TechnoSeal® CrystalShake BC
High Strength Dry-Shake Crystalline Concrete Waterproofing System
TechnoSeal® CrystalShake BC is new generation hydrophilic crystalline waterproofing and permeability reducing dry-shake powder, effective in enhancing concrete impermeability and durability by effectively sealing concrete surface pores and capillaries and reducing the shrinkage cracks. TechnoSeal® CrystalShake BC is applied as a dry-shake to the fresh concrete surface and trowelled into the concrete during the final finishing, where it penetrates deeply into the concrete mass. The dry shake broadcast method produces a smooth finished floor suitable for typical traffic or application of common floor finishes.
Features:
- Chemical Resistance- Highly resistant to aggressive chemicals, Allows concrete to breathe and provides a range of protection from freeze/ thaw cycles, aggressive subsoil waters, sea water, carbonates, chlorides, sulfates and nitrates.
- Waterproofing- Stops water movement through concrete, becomes integral part of the structure.
- Corrosion- Protects reinforcing steel against corrosion.
- Sealing- Waterproofs minor cracking & seal hairline cracks up to 0.5mm.
- Permeability- Resists permeation of water from positive & negative side of the concrete.
- Chemical activation- its waterproofing capability increases with time. I.e. it remains permanently active.
- Abrasion- Does not get affected by surface wear or abrasion, once the penetration is complete.
- Hydrostatic pressure- Resists extreme hydrostatic pressure from either positive or negative surface of the concrete slab becomes an integral part of the concrete.
- Protection- Protects concrete against contaminated water & corrosion.
- Zero VOC- TechnoSeal® CrystalShake –BC contain zero volatile organic compounds and are safe for use both outdoors and in confined indoor spaces.
